Hi Ellie, fish on its own can cause mercury poisoning, even without amalgams. Carlsons cod liver oil "was" said to be mercury free, but someone on another forum got severe poisoning symptoms from it and had to stop taking the stuff, so evidentally it does indeed contain mercury and obviously enough to give someone I know an attack.

So it's a case of sometimes having to give up things that might be risky, evne if you enjoy them. Sugar is one of the worst things you can be eating and it's the hardest to give up (I should know, I am a sugar addict and had to get it out of my diet).

But if you want to feel better? You might want to get tough and try eliminating it (but again, it's up to you).

Whatever you do, I wish you well and hope you can gain some further health or stength in the meantime.
